Description

經改質的聚合物材料及複合式安定劑組成物
本發明是有關於一種經改質的聚合物材料,特別是指一種透過一包括特定的含磷有機抗氧化劑及含硫羧酸鹽化合物的複合式安定劑組成物將烯烴系聚合物或乙烯/醋酸乙烯酯共聚物改質之經改質的聚合物材料。
聚合物基材,例如烯烴系聚合物、乙烯/醋酸乙烯酯共聚物具有良好的化學穩定性、機械強度、電氣絕緣性及製品尺寸安定性,並具有無毒性且易於加工等優點,因而被廣泛應用作為各種產品。聚合物基材雖具有上述優點,但上述聚合物基材在熱能作用下容易被氧化降解,造成黃變以及機械性質下降。
因此,為了防止上述聚合物基材的氧化降解,可在加工成型製程中加入抗氧化劑來降低聚合物基材的氧化降解作用,以增強聚合物基材的機械性質及耐熱性;然而,抗氧化劑本身可能導致聚合物基材帶色及加工穩定性下降。此外,一般在加工成型製程中會再加入制酸劑,是為了抑制酸性物質造成聚合物基材降解,然 而,某些制酸劑的種類或者添加量較多時,也會導致聚合物基材帶色及加工穩定性下降。
因此,本發明之第一目的,即在提供一種經改質的聚合物材料,其在加工成型製程中,能夠維持較佳的顏色穩定性及加工穩定性。
於是,本發明經改質的聚合物材料包含:一聚合物基材,是選自於烯烴系聚合物、乙烯/醋酸乙烯酯共聚物或上述之組合;及一複合式安定劑組成物,包括:一種選自於化學式1至化學式8中至少一者的含磷有機抗氧化劑,及一種選自於化學式9至化學式12中至少一者所示的含硫羧酸鹽,
【化學式7】
在化學式1至化學式7中,R11至R13、R21至R26、R31至R35、R41至R48、R51至R56、R61至R64,及R71至R78各自獨立地表示氫、第三丁基、異丙苯基或C1至C8直鏈烷基;T 表示C1至C18烴基或,R65至R67各自獨立地表 示氫、第三丁基、異丙苯基或C1至C8直鏈烷基;Z41、Z42、Z51及Z61各自獨立地表示O、S或C1至C4伸烷基, 在化學式9中,Mq+表示Ca2+、Mg2+、Ba2+、Zn2+或Al3+,q表示2或3,t表示0至6的整數,R91表示氫或C1至C18烷基,R92表示C1至C30烷基、C6至C18芳烴基或R93OOC-(CH2)k-,其中,R93表示C1至C30烷基或C6至C18芳烴基,k表示1至5的整數, 化學式10中,X11及X12各自獨立地表示Ca2+、Ba2+、Mg2+或Zn2+,Y11及Y12各自獨立地表示C1至C30烷基或C6至C18芳烴基,a及b各自獨立地表示1至6, 化學式11中,p表示1至9的整數,X21表示Ca2+、Ba2+、Mg2+或Zn2+,G1及G2各自獨立地表示 ,其中,c及d各自獨立地表示1 至6,且當p2時,多個G1可為相同或不同,多個X21可為相同或不同, 在化學式12中,X31表示Ca2+、Ba2+、Mg2+、Zn2+,Y31表示C1至C30烷基、C6至C18芳烴基或R93OOC-(CH2)k-,其中,R93表示C1至C30烷基或C6至C18芳烴基,k表示1至5的整數。
因此,本發明之第二目的,即在提供一種複合式安定劑組成物,是用於改質上述的聚合物基材。
於是本發明複合式安定劑組成物包含:一種選自於化學式1至化學式8中至少一者的含磷有機抗氧化劑,以及一種選自於化學式9至化學式12中至少一者所示的含硫羧酸鹽。其中,該化學式1至12是如上所述,故不再贅述。
本發明之功效在於:透過在該聚合物基材中添加含有特定的含磷有機抗氧化劑及含硫羧酸鹽的該複合式安定劑組成物,使得該經改質的聚合物材料在加工製程中能維持良好的顏色穩定性及加工穩定性,繼而製得高品質的成型品。

<實施例1至17>經改質的聚合物材料
依據表1所示的組成成分及比例(重量份),將100重量份聚丙烯或100重量份聚乙烯與複合式安定劑組成物在25℃下均勻混合,分別得到實施例1至17的經改質的聚合物材料E1'至E17'。
<比較例1至21>經改質的聚合物材料
依據表2所示的組成成分及比例(重量份),將100重量份聚丙烯或100重量份聚乙烯與安定劑組成物在25℃下均勻混合,分別得到比較例1至21的經改質的聚合物材料CE1'至CE21'。
[評價測試]
將上述經改質的聚合物材料E1'至E17'以及CE1'至CE21'分別以雙螺桿押出機(台灣弘煜機械公司試驗機PSM20A)混合押出(溫度設定為190至230℃,螺桿轉速為200轉/分鐘,進料速度為6轉/分鐘),再經過冷卻、風乾、切粒、乾燥,製備出樣品E1至E17及CE1至CE21。將樣品E1至E17及CE1至CE21分別重複進行上述押出、冷卻、風乾、切粒、乾燥步驟,以評估樣品在經過多次加工成型的程序後黃色度及熔融指數的變化,黃色度的變化越小代表經改質的聚合物材料在加工成型製程中的顏色穩定性越 佳,熔融指數的變化越小代表經改質的聚合物材料在加工成型製程中的加工穩定性越佳。
1.黃色色差(△b*值)
使用色差儀(為HunterLab公司的ColorQuest XE)分別測量樣品E1至E17及CE1至CE21在第3次及第5次押出後相較於第1次押出的色差值(△b*值),結果如表3及表4所示。
2.熔融指數(melting index,MI)變化(△MI)
使用實驗室熔融指數儀(為Dynisco公司的Laboratory Melt Indexer LMI D4004)分別測量樣品E1至E17及CE1至CE21在第3次及第5次押出後相較於第1次押出的熔融指 ,結果如表3及表4所示。
由表3及表4可以得知,由實施例1至17製得的樣品E1至E17,經第3次押出的△b*值在2.66以下,經第5次押出的△b*值在5.04以下,然而,由比較例1至21製得的樣品CE1至CE21,經第3次押出的△b*值在3.12以上,經第5次押出的△b*值在6.12以上,顯示相較於比較例1至21使用安定劑組成物,實施例1至17經改質的聚合物材料透過使用該複合式安定劑組成物,使得經改質 的聚合物材料具有較佳的顏色穩定性,進而使得所製得的樣品具有較低的黃色色差(△b*值),黃變較不明顯。
根據熔融指數變化(△MI)的結果,由實施例1至17製得的樣品E1至E17,經第3次押出的△MI在161.58%以下,經第5次押出的△MI在258.64%以下;然,由比較例1至21製得的樣品CE1至CE21,經第3次押出的△MI在175.79%以上,經第5次押出的△MI在314.41%以上,顯示相較於比較例1至21使用安定劑組成物,實施例1至17經改質的聚合物材料透過使用該複合式安定劑組成物,使得經改質的聚合物材料具有較佳的加工穩定性(物性),進而使得所製得的樣品具有較低的熔融指數變化(△MI)。
綜上所述,本發明透過在該聚合物基材中添加含有特定的含磷有機抗氧化劑及該含硫羧酸鹽的該複合式安定劑組成物,使得該經改質的聚合物材料在加工製程中能維持良好的顏色穩定性及加工穩定性,故確實能達成本發明之目的。
惟以上所述者,僅為本發明之實施例而已,當不能以此限定本發明實施之範圍,凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾,皆仍屬本發明專利涵蓋之範圍內。
